Infrared gas detector for hydrocarbon gases SearchPoint Optima Plus

The SearchPoint Optima Plus hydrocarbon gas detector

The Honeywell Searchpoint Optima Plus is a high performance fixed infrared hydrocarbon gas detector - ATEX certified - with a very large library of flammable combustible gases with nearly a 100 available calibration curves making it the most versatile infrared gas detector on the market.

A high performance infrared gas detector

The Searchpoint Optima Plus hydrocarbon gas detector uses an infrared double beam measurement technology with an ultra-fast response timecompared to conventional gas detectors with catalytic filament. It needs reduced routine maintenance and has a secure operation thanks to an integrated self-test.

Advanced algorithms for internal fault diagnosis and rejection of false alarms ensure optimum operational integrity. With its high-performance optical unit and its robust stainless steel housing, it is particularly suitable for the most demanding industrial applications.

The SearchPoint Optima Plus gas detector has the HART® communication protocol (Highway Addressable Remote Transducer) to access complete diagnosis, configuration or calibration information from a control room or through a HART® portable device
